But the result was probably fair on Swansea, who had every reason to claim Marcus Rashford dived for the penalty that Rooney converted.

Man Utd 1-1 Swansea: Team has played too many games in April - Jose Mourinho

Super Sigurdsson saves Swans

Swansea were the better side for much of the first half, enjoying the majority of possession as a sluggish United had to rely on David de Gea to make smart saves from Fernando Llorente and Jordan Ayew.

The visitors looked to have been deflated by the controversial penalty on the stroke of half-time, but were rejuvenated by the introduction of Leroy Fer on the hour mark.

Bailly then had to be replaced on 60 minutes after injuring his ankle in a challenge with Llorente, prompting Mourinho to begin his own fake warm-up on the touchline.

"At the moment, we can walk from the bed to the toilet and break a leg," he said.

United were at least boosted by Juan Mata's return to the bench. The Spanish midfielder was feared to be out for the season after groin surgery.

What's next?

United travel to Spain for Thursday's Europa League semi-final first leg against Celta Vigo. Their next Premier League match is at Arsenal on Sunday.

Of their remaining three games, Swansea face perhaps their sternest test on Saturday, when Everton visit south Wales.

'We lost players and we lost points'

Manchester United manager Jose Mourinho: "We lost players and we lost points, so today was a bad day.

"We did not look tired and exhausted, we are tired and exhausted. You cannot isolate the performance out of context.

"This is the ninth match of April, it is not human. We have a squad of 22 that is reduced to 13 or 14 players. The players are very tired."

Clement proud of Swansea performance

Swansea City manager Paul Clement: "My players clearly thought it wasn't a penalty, and seeing the replay the player [Marcus Rashford] has deceived the referee. It's clear. There's no other way to look at it.

"The ref seemed to have some doubts because there was a big delay and I spoke to him afterwards and he said he was only receiving confirmation from his assistants. It was a mistake. He went down way before there was contact.

"It's still very tight at the bottom. We are just concentrating on doing the best we can. Our form over the past two games has been good, we have to keep this going until the very last game of the season."

Golden Gylfi - the stats

Manchester United have set a new club record for the longest unbeaten run within a single top-flight season (25 games, W13 D12).

United have reached double figures for home league draws for only the second time in their history (11 in 1980-81).

Rooney has had a hand in seven goals in his past seven Premier League appearances against Swansea (three goals, four assists).

Rooney is the first United player to score 20 Premier League penalties for the club.

Sigurdsson has been directly involved in 21 of Swansea's 40 Premier League goals this season (nine goals, 12 assists).

Sigurdsson has become the first player to score in three consecutive Premier League away appearances at Old Trafford since Sergio Aguero in April 2015.

The Icelandic midfielder has scored more direct free-kick goals since the start of 2014-15 than any other player (six).
